Anesthesiologists ultrasound-guided regional anesthesia core curriculum: a Delphi consensus from Italian regional anesthesia experts.

INTRODUCTION: The need for a standardized core curriculum in regional anesthesia has become essential, particularly with the integration of ultrasound revolutionizing and exponentially increasing clinical practice and possibilities. In fact, numerous novel techniques, often overlapping, can confuse practitioners. This study aims to establish a core curriculum for upper limb, lower limb, paraspinal and fascial plane blocks for residency training, addressing potential educational gaps caused by the multitude of techniques, through a Delphi consensus process involving recognized Italian regional anesthesia experts. METHODS: A steering committee was formed in order to select a panel of experts in regional anesthesia. A three-round Delphi consensus was planned: two rounds of electronic voting and a final round of mixed electronic voting and round table discussion. The consensus was defined as ≥ 75% agreement for inclusion and lower than ≤ 25% agreement for exclusion from the core curriculum list. Techniques reaching the 50% threshold were included with low consensus. RESULTS: Twenty-nine techniques were selected to be included in the ultrasound-guided regional anesthesia core curriculum. Twenty-two were included with strong consensus: Upper limb: interscalene brachial plexus block, supraclavicular brachial plexus block, infraclavicular brachial plexus block, axillary brachial plexus block, intermediate cervical plexus block Lower limb: femoral nerve block, pericapsular nerve group block, adductor canal block, sciatic nerve block (transgluteal approach, infragluteal approach, and at the popliteal fossa), ankle block Paraspinal/fascial plane blocks: erector spinae plane block, deep serratus anterior plane block, superficial pectointercostal plane block, interpectoral plane block, pectoserratus plane block, rectus sheath block, ilioinguinal iliohypogastric nerves block, transversus abdominis plane block (with subcostal and midaxillary approaches) The remaining seven techniques were included with low consensus: superficial cervical plexus block, lumbar plexus block, fascia iliaca block (suprainguinal approach), anterior quadratus lumborum block, lateral quadratus lumborum block, paravertebral block, and serratus anterior plane block. CONCLUSIONS: This curriculum aims to standardize training and ensure that residents acquire the essential skills required for effective and safe practice regardless of the residents' subsequent specialization. By incorporating these techniques, educational programs can provide a structured and consistent approach to regional anesthesia, enhancing the quality of patient care and improving outcomes.

Does epidural analgesia influence labor progress in women aged 35 or more?

BACKGROUND: During the last decades, the age of pregnant women significantly increased. The incidence of maternal and labor complications is higher among older women, but conclusive data have not been delivered whether labor epidural analgesia (EA) may affect the duration of labor and delivery outcomes in this population of patients. The aim of this study is to evaluate the effect of EA among women aged over 35 years. METHODS: We retrospectively reviewed medical records of all, singleton, at term deliveries, laboring with EA, between December 2011 and October 2017. Women aged ≥35 years (study group) were compared with women aged <35 years (control group) to evaluate EA effects on the duration of labor and neonatal outcome. RESULTS: The study enrolled 459 women with EA: 122 women were included in the study group and 337 in the control group. The multiple regression analysis showed that parity was an independent variable for a shorter dilation period (p = .002), second stage length (p = .0001) and for the total labor duration (p = .0001); neonatal weight was significant for a shorter dilation period (p = .005) and for the total labor duration (p = .002); maternal age and cervical dilatation at the beginning of EA did not influence neither the period of the labor stages nor the total labor duration (p > .05). CONCLUSIONS: Results of this study indicate that women aged ≥35 with EA may have labor duration and neonatal short-term outcomes similar to younger women with EA.

Choice and management of vascular access in the context of COVID-19 outbreak in Italy: Recommendations from clinical practice.

On April 2020, during the outburst of the COVID-19 pandemic in Italy, the SIAARTI ("Società Italiana di Anestesia, Analgesia, Rianimazione e Terapia Intensiva") Research Group on Vascular Access has formulated some essential recommendations for the optimization of the selection, insertion, and maintenance of the vascular access devices, with the aim of guarantee the operator safety, ensure the effectiveness of the maneuvers, and reduce the risk of complications. Here we describe the key elements of clinical management of vascular access in patients affected by COVID-19.

A Call to Action by the Italian Mesotherapy Society on Scientific Research.

Mesotherapy (local intradermal therapy, LIT) is a technique used to slowly spread drugs in tissues underlying the site of injection to prolong the pharmacological effect with respect to intramuscular injection. Recommendations for proper medical use of this technique have been made for pain medicine and rehabilitation, chronic venous disease, sport medicine, musculoskeletal disorders, several dermatological conditions, skin ageing, and immune-prophylaxis. Although mesotherapy is considered a valid technique, unresolved questions remain, which should be answered to standardize methodology and dosing regimen as well as to define the right indications in clinical practice. New randomized controlled trials are needed to test single products (dose, frequency of administration, efficacy and safety). Even infiltration of substances for dermo-cosmetic purposes must be guided by safety and efficacy tests before being proposed by mesotherapy. In this article, we put forth a preclinical and clinical research plan and a health technology assessment as a call to action by doctors, researchers and scientific societies to aid national health authorities in considering mesotherapy for prevention, treatment and rehabilitation paths.

Effectiveness and safety of lidocaine patch 5% to treat herpes zoster acute neuralgia and to prevent postherpetic neuralgia.

Herpes zoster is often associated to acute neuralgia and postherpetic neuralgia (PHN). Their therapeutic management is still challenging: among therapeutic options, lidocaine patch 5% was rarely used in acute neuralgia on lesional skin, and its efficacy to prevent PHN was never studied. The efficacy and tolerability of lidocaine patch 5% was evaluated in 38 patients with acute neuralgia (19) and PHN (19). Pain intensity was investigated using DN4 questionnaire and NRS-11 scale at baseline and at week 2, 4, and 8. The use of rescue therapy was also evaluated. A significant reduction of DN4 and NRS-11 was observed already at W2, with further improvement at W4 and W8. A complete response to treatment (DN4 and NRS-11 = 0) at week 8 was higher in patients with acute neuralgia (63.2%) than PHN (31.6%). Rescue therapy gradually decreased in acute neuralgia patients from week 2 (57.9%) to week 8 (10.5%), with only two patients needing neuroleptics. In PHN patients rescue therapy remained stable (68.4%). According to our results, lidocaine patch 5% applied on lesional skin was well tolerated and ensured a rapid pain relief in acute neuralgia; if early used, it prevented PHN in almost all patients.

Search for SARS-CoV-2 RNA in platelets from COVID-19 patients.

The frequent finding of thrombocytopenia in patients with severe SARS-CoV-2 infection (COVID-19) and previous evidence that several viruses enter platelets suggest that SARS-CoV-2 might be internalized by platelets of COVID-19. Aim of our study was to assess the presence of SARS-CoV-2 RNA in platelets from hospitalized patients with aconfirmed diagnosis of COVID-19. RNA was extracted from platelets, leukocytes and serum from 24 COVID-19 patients and 3 healthy controls, real-time PCR and ddPCR for viral genes were carried out. SARS-CoV-2 RNA was not detected in any of the samples analyzed nor in healthy controls, by either RT-PCR or ddPCR, while RNA samples from nasopharyngeal swabs of COVID-19 patients were correctly identified. Viral RNA was not detected independently of viral load, of positive nasopharyngeal swabs, or viremia, the last detected in only one patient (4.1%). SARS-CoV-2 entry in platelets is not acommon phenomenon in COVID-19 patients, differently from other viral infections.

Association of Neutrophil Activation, More Than Platelet Activation, With Thrombotic Complications in Coronavirus Disease 2019.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 infection is associated with hypercoagulability, which predisposes to venous thromboembolism (VTE). We analyzed platelet and neutrophil activation in patients with coronavirus disease 2019 (COVID-19) and their association with VTE. METHODS: Hospitalized patients with COVID-19 and age- and sex-matched healthy controls were studied. Platelet and leukocyte activation, neutrophil extracellular traps (NETs), and matrix metalloproteinase 9, a neutrophil-released enzyme, were measured. Four patients were restudied after recovery. The activating effect of plasma from patients with COVID-19 on control platelets and leukocytes and the inhibiting activity of common antithrombotic agents on it were studied. RESULTS: A total of 36 patients with COVID-19 and 31 healthy controls were studied; VTE developed in 8 of 36 patients with COVID-19 (22.2%). Platelets and neutrophils were activated in patients with COVID-19. NET, but not platelet activation, biomarkers correlated with disease severity and were associated with thrombosis. Plasmatic matrix metalloproteinase 9 was significantly increased in patients with COVID-19. Platelet and neutrophil activation markers, but less so NETs, normalized after recovery. In vitro, plasma from patients with COVID-19 triggered platelet and neutrophil activation and NET formation, the latter blocked by therapeutic-dose low-molecular-weight heparin, but not by aspirin or dypiridamole. CONCLUSIONS: Platelet and neutrophil activation are key features of patients with COVID-19. NET biomarkers may help to predict clinical worsening and VTE and may guide low-molecular-weight heparin treatment.

Mesotherapy: From Historical Notes to Scientific Evidence and Future Prospects.

Intradermal therapy, known as mesotherapy, is a technique used to inject a drug into the surface layer of the skin. In particular, it involves the use of a short needle to deposit the drug in the dermis. The intradermal microdeposit modulates the drug's kinetics, slowing absorption and prolonging the local mechanism of action. It is successfully applied in the treatment of some forms of localized pain syndromes and other local clinical conditions. It could be suggested when a systemic drug-sparing effect is useful, when other therapies have failed (or cannot be used), and when it can synergize with other pharmacological or nonpharmacological therapies. Despite the lack of randomized clinical trials in some fields of application, a general consensus is also reached in nonpharmacological mechanism of action, the technique execution modalities, the scientific rationale to apply it in some indications, and the usefulness of the informed consent. The Italian Mesotherapy Society proposes this position paper to apply intradermal therapy based on scientific evidence and no longer on personal bias.

Anesthesia Experience for Open Gastrostomy with Ultrasound-Guided Erector Spinae Plane Block: A Case Report.

From the first description in 2016 till today, hundreds of studies have extensively presented Erector Spinae Plane block as an excellent perioperative analgesic technique especially in a multimodal pain management scenario. Only in few cases, this technique was used alone to provide surgical anesthesia.

Pectoralis (PecS) nerve block 1 for port-a-cath removal and central venous catheter (CVC) replacement.

Aim The use of PecS block 1 as perioperative analgesia for a central catheter removal -reimplantation combined procedure. Methods A 55-year-old woman suffering from peritoneal metastases from gastric cancer needed to have a port-a-cath implanted for infection removed and to have a central venous catheter (CVC) implanted in the homolateral axillary vein due to patient's history of deep vein thrombosis of the right upper limb. We used PECS 1 block for perioperative analgesia. Results Compared to the traditional catheter implantation technique, reduction in the doses of local anaesthetics, shortening in the execution time, less intra-procedural bleeding, better patient's compliance, and no need for a rescue dose of local anaesthetic were observed. Conclusion The PEC1 block was effectively and safely used to remove an infected port-a-cath and to place a CVC on the same side. We hypothesize that it may be useful also for simple port-acath positioning.

Epidural Corticosteroids, Lumbar Spinal Drainage, and Selective Hemodynamic Control for the Prevention of Spinal Cord Ischemia in Thoracoabdominal Endovascular Aortic Repair: A New Clinical Protocol.

INTRODUCTION: In patients undergoing thoracoabdominal aorta repair, spinal cord ischemia (SCI) remains one of the most common and important complications resulting in transient paraparesis through to permanent flaccid paraplegia. In this manuscript, after a brief introduction to spinal cord ischemia complication and its prevention in thoracoabdominal endovascular aortic repair (TEVAR), we propose a new clinical protocol potentially able to prevent such complication. METHODS: The proposed protocol suggests the use of high dosages of corticosteroids by epidural route, along with drainage of cerebrospinal fluid and controlled vascular hypertension, to reduce the incidence of SCI in TEVAR. Moreover, we paid particular attention to the control of the hemodynamic parameters to obtain adequate peripheral tissue perfusion (oxygen delivery), including in the spinal cord. RESULTS: We applied this new protocol in 50 consecutive patients treated with TEVAR for thoracoabdominal aortic aneurysms (TAAs); 47 patients completed the procedure: 27 patients Crawford type I and 20 Crawford type II. Three patients died during surgery because of untreatable aneurysm rupture. The results show that in all patients there were no cases of SCI, after 5 days from TEVAR. DISCUSSION: To the best of our knowledge, there are no clinical studies on the use of epidural corticosteroids in patients undergoing treatment of aortic syndrome (both in "open surgery" and endovascular aortic repair). This initial study on 50 consecutive patients has shown that the clinical protocol used could be of great interest to prevent one of the worse complications of TEVAR. Its limitations are the low number of patients studied till now, and the non-randomized protocol adopted. Further studies would be necessary. CONCLUSION: Our experience and the results obtained with this new perioperative protocol with epidural corticosteroid and accurate hemodynamic control have been encouraging and it seems a valid proposal to be explored in future by well-structured prospective, randomized protocols.

Ultrasound Guided Continuous Sciatic Nerve Block for Acute Herpetic Neuralgia.

Herpes Zoster (HZ) is the reactivation of a well-known viral disease which manifests itself with painful skin lesions. An effective analgesic method during the acute phase of HZ can contribute to decrease the incidence of postherpetic neuralgia (PHN) by reducing neural sensitization. Sciatic nerve block (SNB) is useful in the management of distal lower extremity pain sustained by the sciatic nerve. We describe our experience with a continuous ultrasound guided subgluteus sciatic nerve block in a patient with herpetic neuralgia- (HN-) related refractory acute left leg pain.
